Elvis Nickel Alloys, located in Houston, USA, stands out as a top manufacturer and supplier of Duplex Steel 2205 Fasteners. These fasteners are crafted for exceptional strength, corrosion resistance, and reliability, especially in tough industrial settings. Made from UNS S32205 / S31803, they feature a unique dual-phase microstructure (austenitic-ferritic) that provides outstanding protection against pitting, crevice corrosion, and chloride stress corrosion cracking. You can find them in various forms like bolts, nuts, washers, screws, and studs, all adhering to international standards such as ASTM A479, ASTM A276, and DIN. This makes them perfect for structural and mechanical applications in marine, chemical, and oil & gas industries.
Duplex Steel 2205 Fasteners are made up of 22–23% chromium, 4.5–6.5% nickel, 2.5–3.5% molybdenum, 0.14–0.2% nitrogen, along with balanced amounts of manganese, silicon, and iron. This specific blend results in a PREN greater than 35, ensuring top-notch corrosion resistance. These fasteners boast a tensile strength of around 620–850 MPa and a yield strength of at least 450 MPa, along with impressive impact toughness, even in freezing temperatures. Their unique combination of strength and ductility, along with a lower risk of distortion under thermal stress, makes them a go-to choice for high-load and high-temperature applications.
